Desperately Seeking T3

I am looking for a reputable source of T3 and I live in the US. I am hypothyroid (have been for about 20 years with the same endocrinologist) and have been looking on sites online but I am skeptical about spending what little money I have with someone I know nothing about. I am on Synthroid 137 mcg and my latest test scores are as follows:

TSH: 0.46 (range 0.40-4.50 mlU/L)

T4, Free: 1.4 (range 0.8-1.8 ng/dl)

T3, Free: 2.8 (range 2.3-4.2 pg/mL)

Thyroglobulin Antibodies: <1 (range < or =1 IU/mL)

Thyroid Periodase Antibodies: <1 (range <9 IU/mL)

Per the coordinator on this site, my body is not converting the T4 into T3. This is why I am still suffering with anxiety, depression, severe dry skin and a host of other problems. I have looked on Amazon and a few other internet sites and I am really afraid to just order from an unknown vendor as I do not know if what I am getting will be what I need or is the real thing. I really need T3 and my doctor has NEVER and will not prescribe. I had to recently reschedule my doctor appointment due to recent financial problems and cannot see my doctor again until March. I am also trying to find another endo in my area who will prescribe T3. Unfortunately, my insurance will no longer pay for T3 so it will be out of pocket no matter the source. I am really desperate for some help. Thank you.

Your FT3 is low so adding some T3 will raise it but it will also lower your TSH so you will probably have to come clean with your doctor when you have your next thyroid test as your doctor may think you are overmedicated if TSH is suppressed.

I would buy a pillcutter to quarter the 25mcg T3 tablets and start by adding 6.25mcg T3 to your current 137mcg Synthroid dose. You can take them together. If you tolerate the T3 okay and feel you need more, after 2 weeks you can add a second 6.25mcg dose at bedtime (at least two hours after food and drink). Hold at 12.5mcg T3 for 6-8 weeks and have a thyroid functions test including FT3 before increasing further.

Thyroid antibodies are negative for autoimmune thyroiditis (Hashimoto's).
